Facebook has asked the larger United States banks to share detailed financial information about customers as it seeks to boost user engagement and enhance the Messanger app. According to The Wall Street Journal,Facebook increasingly seeks to be a platform where people buy and sell goods and services, in addition to connecting with friends. Over the past year, the social media giant has asked JPMorgan Chase, Wells Fargo, Citigroup, and U.S. Bancorp to discuss potential offerings it could host for bank customers on Facebook Messenger.

Facebook has talked about a feature that would show its users their checking-account balances, said people familiar with the matter. It has also pitched fraud alerts, some of the people have said.

These talks are taking place as Facebook faces several investigations over its ties to political analytics firm Cambridge Analytica, which accessed data on as many as 87 million Facebook users without their consent. One large U.S. bank pulled away from talks due to privacy concerns, some of the people said. The ploy is to get people to spend more time on Facebook Messenger.
